The Brahman priest (brahma) being thus the recognized head of the sacerdotal order (brahma), which itself is the visible embodiment of sacred writ and the devotional spirit pervading it (brahma), the complete realization of theocratic aspirations required but a single step, which was indeed taken in the theosophic speculations of the later Vedic poets and the authors of the Brahmanas (q.v.), viz.
The gradual elaboration of the sacrificial ceremonial, as the all-sufficient expression of religious devotion, and a constantly growing tendency towards theosophic and mystic speculation on the significance of every detail of the ritual, could not fail to create a demand for explanatory treatises of this kind, which, to enhance their practical utility, would naturally deal with the special texts and rites assigned in the ceremonial to the several classes of officiating priests.

Geiger Johann Reuchlin (1871), p. 167) introduced him to the Kabbalah, which had great fascinations for one who loved all mystic and theosophic speculation.
Swedenborg's theosophic system is most briefly and comprehensively presented in his Divine Love and Wisdom.
